rubio the saviour. christie and his weight. and ashley judd in the crosshairs. first of all, here's marco rubio on the cover of "time" magazine is he the savour of the party, giving the response to the state of the union. he is pretty out front there as a leading voice for 2016. >> he is a huge republican voice, and that's a good thing for the party. i'm a fan. if he's thinking of running for president, it's awfully early. >> and risk overexposure. >> the immigration fight. >> rubio is not to be focused on immigration in his response of the state of the union. he's going to be talking about political philosophy, how limited government helps the middle class, which will help him with conservatives. >> katty kay, here you have chris christie taking on his weight on his terms. we just showed the pictures of him on letterman. he takes out the donut. and he said i'm the healthiest fat guy you know. he is taking this issue on. it would be an issue if he ran. >> he joked about it then, but he spoke about it much more seriously, about his efforts to try and lose weight,
